Detailed explanation-1: -Sexual reproduction results in infinite possibilities of genetic variation. In other words, sexual reproduction results in offspring that are genetically unique. They differ from both parents and also from each other.

Detailed explanation-2: -There are two main forms: sexual and asexual reproduction. In sexual reproduction, an organism combines the genetic information from each of its parents and is genetically unique. In asexual reproduction, one parent copies itself to form a genetically identical offspring.

Detailed explanation-3: -Genetic variation is a term used to describe the variation in the DNA sequence in each of our genomes. Genetic variation is what makes us all unique, whether in terms of hair colour, skin colour or even the shape of our faces.

Detailed explanation-4: -each child is different because your sperm cells don’t all have the same DNA. And the same goes for your wife’s eggs. Each sperm and each egg has a never before seen combination of DNA. This happens because even though each sperm and egg gets half of the parent’s DNA, they don’t each get the same half.

Detailed explanation-5: -Sexually reproduced offspring are never identical to their parents. Many species, of animals and plants, including humans reproduce sexually. Specialised cells from a female (egg cell/ova) and male (sperm)fuse together to begin the development of a new individual.
